REALPRO series aims to meet professional and amateur photographer demands that are becoming more varying and specific.Protect your image from UV lightREALPRO UV is a multi-purpose fine-weather filter that blocks UV light the reason for unclear and hazy photos on a bright day. REALPRO UV filter adopts UV-CUT glass that blocks unwanted UV spectrum before light comes out from the filter. This type of glass has a slight yellow tint, there is no negative effect on the image. REALPRO UV filter is a universal filter, because it also serves as a permanent lens protector.The filter that stays clear for a long time.The one important feature of REALPRO series is Anti-Stain Coating (ASC) that represents ne.w generation of Kenko coating technology.Thanks to a ne.w formula of coating material the surface of REALPRO UV filter will make moisture and water drops to bead up and slip down leaving filter clean. Thus, you will not need to clean filters for a long time and maintenance will become incredibly easier and safer. Due to smooth filter surface dust and smudges can be wiped more easily because they do not stick on to the glass so strongly. Time you spend on the after-care routine will be considerably shortened and the cleaning process will not bother you any more. This feature is highly valued by extreme photographers who are shooting outdoors in various weather conditions.Every single light will reach camera sensor for clear and sharp imageSince the sensor of digital SLR or mirrorless cameras becomes more sensitive to light coming through the lens, Anti-Reflection Multi Coating is a must for photographic filters. Kenko REALPRO UV with Anti-Reflection Multi Coating technology that has already obtained a general standard for each Kenko filter will give you maximum light transmission and protection from flares and ghosting caused by parasite reflections.Slim FrameUse with any lens and with no loss of light. REALPRO Protector adopts ultra thin frames to avoid vignetting effect on wide and super wide angle lenses.Knurling Edge FrameThe frame of REALPRO Protector is equipped with a knurling surface to prevent slipping, making attachment and removal easy and stress-free. Black Almite FrameTo reduce to minimum any unwanted reflections REALPRO Protector adopts black aluminium satin finish almite frame. Satin finish will increase friction between fingers and frame for quick operation and satin black frame will minimise internal reflections.Black Rimmed GlassTo reduce the internal light reflections off the edge of the filter glass Kenko uses the technology of black rimming. The outer rim of the glass plate is treated with a specific black ink to prevent any leaking of the light.Wide variety of sizesIn order to meet the demands of as many photographers as possible, REALPRO Circular PL filter is presented in a whole line up of sizes from 37mm for non-reflex cameras to 95mm and even 105mm for high-end super tele lenses and broad-casting.UV Protected CaseEvery REALPRO UV filter comes with a durable reusable plastic case with UV-Cut function.
